A respirator 10 that has a mask body 14 and a malleable nose clip 12 . The mask body 14 is adapted to fit at least over the nose and mouth of a person to define an interior gas space that is separate from the exterior gas space. The mask body 14 has the nose clip 12 secured to it and can include at least one layer of filter media 20 . The malleable nose clip 12 comprises a semi-crystalline polymeric material that has an integrated diffraction intensity ratio of at least about 2.0. The nose clip 12 can be deformed into a desired configuration that enables the mask body 14 to maintain a snug fit over a person's nose when the respirator is worn for extended time periods. Because the nose clip 12 does not need to contain metal, the whole respirator 10 can be easily processed as waste in an incinerator when its service has ended.

The invention discloses an operation method for separating a crust from seeds of tomato paste by a disk huller. The operation method comprises the following steps: the water content of the fed tomato paste is about 10-20 percent, an inclined packing auger provides 2.2 KW power input with the diameter of 650 mm and the power of 17 KW to grind the disk huller at a rated speed; and a manual handle isused for firstly adjusting a grinding disc distance to be 5 mm and a feeding amount to be about 0.8 ton per hour, and then adjusting the grinding disc distance to be 3 mm to feed the ground materialsby 0.4-0.6 ton per hour for once or twice so as to fully separate the crust form the seeds of the tomato paste. The invention overcomes the defect that the prior art can not finish separating the tomato crust form the tomato seeds in a device, adjusts the grinding disc distance of the disk huller by controlling the feeding amount of the tomato paste and grinds the tomato paste twice so that the separation effect of the crust from the seeds of the tomato paste can reach over 96 percent.

The invention discloses linkage double-hoisting mechanisms of a tower crane and a speed regulating method. The tower crane is provided with the two hoisting mechanisms, wherein one hoisting mechanism comprises a single-speed electric motor, a speed reducer I and a winding drum I, the other hoisting mechanism comprises a double-speed electric motor, a speed reducer II and a winding drum II, the winding drum I and the winding drum II are respectively wound with a plurality of steel wire ropes, the steel wire ropes wind around steering pulleys, load-trolleys and lifting hooks of arm ends of the hoisting mechanisms respectively, and the single-speed electric motor, the double-speed electric motor and a controller are connected. The two hoisting mechanisms are used, the steel wire ropes string the two winding drums, the lifting hooks and the load-trolleys of the tower crane, more steel wire ropes can be contained, and requirements of the tower crane for the lengths of the steel wire ropes are met. The hoisting mechanisms at two different steel wire rope linear speeds are adopted, and speed regulation can be easily achieved through combination of the speeds.

A pulverized coal burner capable of realizing efficient ignition and burning and applicable to an asphalt mixing plant comprises a support, a furnace body, a coal feeding pipe, an air guiding device and an ignition system, wherein the air guiding device comprises an air guiding chamber, a variable frequency fan and an air inlet channel; a refractory mortar cast layer is arranged on the side surface of the air inlet channel and is provided with a circular air inlet and a first furnace chamber air channel; the middle of the refractory mortar cast layer is connected with the coal feeding pipe; an ignitor air pipe is sleeved with the coal feeding pipe; a circular air channel is mounted between the ignitor air pipe and the tail end of the coal feeding pipe; the air guiding chamber is further provided with a branch air pipe communicating with the ignitor air pipe; the ignition system comprises an ignitor, an air storage tank and a fuel pipe; the ignitor is arranged at the tail end of the ignitor air pipe; an air cylinder connected with the ignitor is further arranged in the ignitor air pipe; diesel oil is contained in the air storage tank; an air inlet end of the air storage tank is connected with an air compressor; an air outlet end of the air storage tank is connected with the ignitor through the fuel pipe. With the burner, pulverized coal can be sufficiently dispersed, the ignitor can perform ignition easily, and the burning efficiency of the pulverized coal can be improved.

The invention discloses an aluminum film baffle device and a pulse solid engine applying the same. The aluminum film baffle device takes a flexible aluminum film baffle as a fracture element and is matched with a hollow-carved baffle support in a cross-shaped supporting structure. The aluminum film baffle can bear high pressure and cannot be fractured in the direction where the aluminum film baffle is supported by the baffle support while the flexible aluminum film baffle can be fractured easily in the direction where the aluminum film baffle is not supported by the baffle support. One side of the aluminum baffle, which cannot be fractured, is dead against a first pulse grain so as to prevent the aluminum baffle from being fractured during the burning process of the first pulse grain of the engine. Therefore, a second pulse grain of the engine can be protected. When the second pulse grain is ignited, the aluminum film baffle rapidly is fractured so that gas passes through the aluminum film baffle device. The device provided by the invention has stable and reliable performance and the material of the baffle is easy to get and process. The fragments of the fractured aluminum film baffle can not affect the operation of the engine and the device has no special requirements on a loading device and an igniter.

The invention provides a transformer for induction hardening. A casing of the transformer is a cylindrical copper casing, a circular primary coil is arranged in the casing, both ends of the casing are respectively connected with a first copper cover plate and a second copper cover plate, the first copper cover plate is provided with a water joint, the first copper cover plate and the second copper cover plate are connected together by a center mandrel, the center mandrel is connected with the second copper cover plate in an insulation way, the second copper cover plate and the center mandrel are respectively and conductively connected with two input electrodes, the casing, the first copper cover plate, the center mandrel, the second copper cover plate and the two input electrodes form a secondary coil together, the primary coil is insulated from the secondary coil, the water joint is also used as a cable input end of the primary coil, and an integral cavity of the casing is a cooling chamber. The transformer has the advantages that the primary coil and the secondary coil are arranged in a circular surrounding way, the integral transformer is cooled by feeding water to the interior of the transformer, the size of the transformer is small, the required installation space is small, the cooling effect is good, impurities accumulated in the transformer can be easily cleaned, and the service life is long.
